[0013] A method for using a demoulding and pushing mechanism for an aluminum ingot casting mold product, the method comprising the following steps:

[0014] When the aluminum ingot in the forming mold needs to be ejected, the driving component is directly controlled to work, and the driving component drives the reciprocating screw and the cam to rotate. At this time, the reciprocating screw uses the threaded action to control the threaded cap and the movable cross plate to move upward. The movable cross plate moves upward and drives the vertical connecting cylinder, the ejection seat, the intermediate rod and the bearing frame to move upward. The cam rotates and squeezes the contact rod, the piston rod and the piston plate to move. When the piston plate moves away from the reciprocating screw, the gas in the piston cylinder is squeezed through the one-way air outlet valve, the vertical connecting cylinder and the air outlet head to be discharged between the forming mold and the aluminum ingot. When the cam protrusion position rotates away from the contact rod, the second elastic component drives the piston plate to reset, and sucks the external gas into the piston cylinder through the one-way air inlet valve.

[0015] The exhaust in the forming mold cooperates with the ejection seat to push the aluminum ingot upward to realize the demoulding and ejection of the aluminum ingot, the carrying frame moves upward, and the magnetic moving plate moves upward away from the magnetic block on the lower side. At this time, the first elastic component drives the extrusion ball to separate from the extrusion groove. At this time, the elastic telescopic rod drives the limit contact plate upward to contact the supporting roller. When the ejection seat will completely eject the aluminum ingot upward from the forming mold, the carrying frame moves upward to a position flush with the upper surface of the forming mold. During the upward movement of the carrying frame, the magnetic moving plate moves close to the upper magnetic block, and the magnetic force squeezes the magnetic moving plate and the extrusion ball to move close to the extrusion groove, and the extrusion limit contact plate is separated from the supporting roller downward. At this time, the linear drive mechanism controls the pushing plate to push the aluminum ingot to the surface of the supporting roller, and then the reciprocating screw drives the threaded cap and the moving cross plate to move downward. The moving cross plate drives the carrying frame and the aluminum ingot to move downward through the middle rod. When the carrying frame moves into the first connecting hole, the control drive component stops working, and the aluminum ingot can be pushed to one side for removal.

[0016] The beneficial effects of the present invention are:

[0017] The present invention provides a driving assembly, a reciprocating screw, a threaded cap, a vertical connecting cylinder, an ejector seat, an air outlet head, a cam, a piston plate, a piston cylinder, a one-way air inlet valve and a one-way air outlet valve. The one-way air outlet valve, a connecting hose, a vertical connecting cylinder and an air outlet head form a gas channel for discharging the gas in the piston cylinder into the forming mold. The driving assembly drives the reciprocating screw and the cam to rotate, so as to control the ejector seat to push the aluminum ingot upward. When the air outlet head enters the forming mold, the air outlet head blows the gas between the aluminum ingot and the forming mold. The gas will act more comprehensively on the side of the aluminum ingot, and cooperate with the ejector seat to achieve full separation between the aluminum ingot and the forming mold, so that the demoulding process is more comprehensive and safer, and the probability of damage to the forming mold or the aluminum ingot is reduced.

[0018] The present invention provides a bearing frame, a supporting roller and an intermediate rod. When the movable cross plate drives the ejection seat to push the aluminum ingot upward, the bearing frame and the supporting roller move upward, cooperate with the pushing plate to push the aluminum ingot to the surface of the supporting roller, and move downward after the ejection seat completes the ejection and demoulding. The supporting roller drives the aluminum ingot to move downward, and the aluminum ingot can be automatically transferred to the surface of the placement table, so that the handling and removal operation is convenient and labor-saving, and the safety hazard is relatively small.

[0019] The present invention provides an extrusion groove, an extrusion ball, a magnetic movable plate, a magnetic block, an elastic telescopic rod and a limiting contact plate. When the limiting contact plate contacts the supporting roller, the supporting roller can be limited. The bearing frame and the supporting roller will not rotate when moving in the vertical direction, thereby ensuring that the aluminum ingot remains stable during the descending process. When the supporting roller is at the uppermost and lowermost positions, the position of the magnetic block corresponds to the position of the magnetic movable plate, and the magnetic force will squeeze the magnetic movable plate and the extrusion ball to move. The extrusion ball controls the extrusion groove and the limiting contact plate to separate downward from the supporting roller. At this time, the supporting roller can rotate smoothly, making it convenient for the aluminum ingot to roll onto or be removed from the supporting roller. BRIEF DESCRIPTION OF THE DRAWINGS

4. The method for using the demoulding and pushing mechanism of the aluminum ingot casting mold product according to claim 3, characterized in that: The method of use comprises the following steps: When it is necessary to eject the aluminum ingot in the forming mold (3), the driving assembly (71) is directly controlled to work, and the driving assembly (71) drives the reciprocating screw (72) and the cam (8) to rotate. At this time, the reciprocating screw (72) controls the threaded cap (73) and the movable horizontal plate (74) to move upward by means of the thread action. When the movable horizontal plate (74) moves upward, it drives the vertical connecting cylinder (76), the ejection seat (77), the intermediate rod (11) and the bearing frame (51) to move upward. When the cam (8) rotates, it squeezes the contact rod (91). , the piston rod (92) and the piston plate (94) move, and when the piston plate (94) moves away from the reciprocating screw rod (72), the gas in the piston cylinder (93) is squeezed through the one-way air outlet valve (97), the vertical connecting cylinder (76) and the air outlet head (78) to be discharged between the forming mold (3) and the aluminum ingot; when the raised position of the cam (8) rotates away from the contact rod (91), the second elastic component (95) drives the piston plate (94) to reset, and sucks the external gas into the piston cylinder (93) through the one-way air inlet valve (96); The aluminum ingot is pushed upward by exhausting air into the forming mold (3) in cooperation with the ejection seat (77) to realize demoulding and ejection of the aluminum ingot. The supporting frame (51) moves upward, and the magnetic moving plate (573) moves upward away from the lower magnetic block (14). At this time, the first elastic component (575) drives the extrusion ball (571) to separate from the extrusion groove (56). At this time, the elastic telescopic rod (55) drives the limit contact plate (53) upward to contact the support roller (52). When the ejection seat (77) completely ejects the aluminum ingot upward from the forming mold (3), the supporting frame (51) moves upward to a position flush with the upper surface of the forming mold (3). During the upward movement of the supporting frame (51), the magnetic moving plate (573) approaches the support roller (52). The upper magnetic block (14) moves, and the magnetic force squeezes the magnetic moving plate (573) and the squeezing ball (571) to move close to the squeezing groove (56), and the squeezing limit contact plate (53) moves downward and separates from the supporting roller (52). At this time, the linear drive mechanism (12) controls the push plate (13) to move and push the aluminum ingot to the surface of the supporting roller (52). Then, the reciprocating screw (72) drives the threaded cap (73) and the movable horizontal plate (74) to move downward. The movable horizontal plate (74) drives the bearing frame (51) and the aluminum ingot to move downward through the intermediate rod (11). When the bearing frame (51) moves into the first connecting hole (4), the control drive assembly (71) stops working, and the aluminum ingot can be pushed to one side and removed.
